I would like to make the suggestion that some tools are removed/simplified/blended/given consistency.
There are a few tools that could use this treatment, but I recently took some time to look at the Extrusion, Reshape, Extend, and Thicken tools when applied to surfaces; all these tools essentially do the same thing, but with a few inconsistencies.
Let's say you have 30 separate square surfaces. If you want to thicken/extrude/reshape/extend 20 of them, one would pre-pick these surfaces select a tool, then click on the screen to do them all at once. The interesting thing here is that the RESHAPE tool and the EXTEND tool will unpick the surfaces while EXTRUSION and THICKEN will not. Naturally, it took me 3 tries to figure this out after trying to use Reshape and Extend before using Extrusion.
It's also interesting that each of the Tool Options are slightly different, so it's not like you can just remove 2 of the tools and let the other tools do their jobs, there has to be some sort of simplification here.
Perhaps you can add all these abilities to one tool? Let Reshape be given a fixed distance with In, Out, and Center, as well as dynamic, the ability to pre-pick, and also work on smooth objects? I think that covers all ground for what this tool could do.
